Austin police are investigating the city's third traffic fatality of the New Year.
Police say just after 4 a.m. Thursday morning the driver of a pickup veered off I-35, flipped over and landed in the grass.
An eye witness to crash called 911 telling police the driver didn't appear to be speeding.
The driver of the truck is at the hospital with unknown injuries and her passenger, a man, was pronounced dead at the scene.
Officers diverted traffic on to the service road for about a mile.
The vehicular homicide team spent a couple of hours processing the scene and will try to piece together what caused the driver to lose control.
2012 was a deadly year on Austin roads with 80 fatalities. Now just three days into the new year officers are wondering how to keep streets safe.
